Memory loss

Hello, Doctor! I would like to inquire about memory impairment.
I have the following situation: my memories mostly only last for about the past two years, and memories from more than two years ago are mostly vague, and sometimes I can't even recall events or experiences I've had.
Here are a few specific examples: when reminiscing with family about past events, I often cannot remember, or I am completely unaware of them.
I have noticed that my memory primarily falls within one to two years.
The second example is that sometimes I can't even recall what I did during my college years, the people I met, or their names; I can only remember a few names.
Additionally, I have almost no memories from high school, middle school, or elementary school, except for significant events like the passing of a relative.
I have no recollection of what I did or what was said during those times.
Sometimes I wonder if there is something wrong with me.
I would like to ask the doctor what kind of condition I might have based on these symptoms and what type of examinations I should undergo.
(P.S.
It seems I have been this way since childhood, only remembering events from about two years prior.)

Hello: The human brain has a limited capacity, especially regarding "working memory." Working memory refers to the level of focus a person has at a given moment.
For example, when a waiter is taking an order from a customer, they must concentrate and remember what the customer has ordered.
However, once the waiter delivers the order to the kitchen, they may forget what the customer ordered.
This state of focused memory is known as working memory, which has a limited capacity, necessitating the selective retention of important information.
This is how human memory functions; it chooses to remember what you deem important due to its limited capacity.
You mentioned that you only remember events from the past 1-2 years, but that is not accurate.
You remember how to walk, eat, write, make phone calls, and use your smartphone; you also remember your home address, how to get to your school, how to reach your workplace, your name, and the faces of your relatives, among other things.
These are not just memories from the past 1-2 years; they have been imprinted in your long-term memory for a long time, and you use them daily.
This is not a disease.
However, you can train your focus, which can enhance your memory.
You might try spending a morning or afternoon without using your phone, messaging apps, or computer, and start by concentrating on reading a book.

More Info

Memory loss can be a concerning issue, especially when it affects your daily life and interactions with others. Based on your description, it seems that you have difficulty recalling events and experiences that are older than two years, while more recent memories are clearer. This phenomenon can be attributed to various factors, and understanding these can help you determine whether you should seek further medical evaluation.

Firstly, it's important to recognize that memory is a complex function of the brain, involving various types of memory systems. The distinction between short-term and long-term memory is crucial here. Short-term memory, or working memory, allows us to hold and manipulate information temporarily, while long-term memory is responsible for storing information over extended periods. The fact that you can recall recent events but struggle with older memories may suggest that your long-term memory retrieval is impaired.

Several potential causes could explain your memory difficulties:
1. Normal Variability: It's not uncommon for people to have varying degrees of memory recall. Some individuals naturally have better memory for recent events and may find it harder to remember details from their past. This variability can be influenced by factors such as attention, emotional significance of events, and the frequency with which memories are revisited.

2. Stress and Anxiety: Psychological factors, including stress and anxiety, can significantly impact memory. If you have experienced high levels of stress or anxiety, it may hinder your ability to recall past events. This is particularly relevant if you have a history of trauma or emotional distress.

3. Depression: Memory issues can also be a symptom of depression. Individuals with depression often report difficulties with concentration and memory, which can lead to feelings of forgetfulness or confusion.

4. Neurological Conditions: In some cases, memory loss can be indicative of neurological conditions such as mild cognitive impairment (MCI) or early-stage dementia. While these conditions are more common in older adults, they can occur in younger individuals as well. If you have concerns about the possibility of a neurological condition, it is essential to consult a healthcare professional.

5. Developmental Factors: You mentioned that you have experienced these memory issues since childhood. This could suggest a developmental aspect to your memory function. Some individuals may have a different memory encoding or retrieval style, which can affect how they recall past experiences.

Given your concerns, it would be advisable to seek a comprehensive evaluation from a healthcare provider, such as a neurologist or a psychologist. They may recommend a series of tests to assess your cognitive function, memory, and overall brain health. These tests could include neuropsychological assessments, brain imaging (like an MRI or CT scan), and blood tests to rule out any underlying medical conditions.

In the meantime, there are strategies you can employ to help improve your memory. Engaging in activities that stimulate your brain, such as puzzles, reading, or learning new skills, can enhance cognitive function. Additionally, maintaining a healthy lifestyle that includes regular physical exercise, a balanced diet, and adequate sleep can support overall brain health.

In summary, while your memory issues may be concerning, they can stem from a variety of factors, ranging from normal variability to psychological influences or neurological conditions. Seeking professional guidance will provide you with a clearer understanding of your situation and help you determine the best course of action. Remember, you are not alone in this, and there are resources available to support you in improving your memory and overall cognitive health.
